Automatic-Leaf Spring Shot Peening Machine
The Leaf Spring Shot Peening Machine is designed for automotive spring manufacturers to improve the fatigue strength and service life of leaf springs after heat treatment.
By using high-speed steel shots to impact the spring surface, the equipment creates a compressive stress layer that helps reduce surface stress and improve durability.
It is widely used for truck leaf springs, trailer springs, and heavy-duty vehicle suspension springs.
Working Principle
After heat treatment, the leaf spring enters the shot peening chamber through the feeding system.
The high-speed rotating impeller projects steel shots onto the spring surface evenly. The impact force changes the surface stress condition and improves the fatigue resistance of the spring.
The main process includes:
Spring loading
Shot peening treatment
Surface cleaning
Finished spring unloading
Improve Fatigue Strength
The shot peening process helps increase the fatigue life of automotive leaf springs under repeated loading conditions.
Uniform Surface Treatment
The optimized shot projection system ensures consistent treatment results for different spring sizes.
Automatic Production
The automatic operating system reduces manual handling and improves production efficiency.
Suitable for Various Springs
The machine can process:
Truck leaf springs
Trailer leaf springs
Commercial vehicle springs
Heavy-duty suspension springs
